What is the force when two materials rub together?

The force when two materials rub together is called friction. Friction is a resistive force that opposes the relative motion or tendency of motion between two surfaces in contact. The magnitude of the frictional force depends on factors such as the nature of the surfaces and the force pressing them together.


Unbalanced force opposing motion between touching surfaces?

The unbalanced force that opposes motion between touching surfaces is called friction. It acts in the opposite direction of the applied force and depends on the nature of the surfaces and the force pressing them together. Friction can be reduced by using lubricants or by increasing the smoothness of the surfaces.


Which is force that resists sliding motion between two surfaces in contact?

The force is called friction.


What are Surfaces that touch food are called?

Surface that touch food are called "food contact surfaces".


What do you call a force that opposes the motion of one surface as it moves across another?

This is one form of the property called friction. It is not a kinetic force, but opposes a force. It is caused by the interaction between molecules of the interacting surfaces. When motion occurs between surfaces, friction may convert mechanical energy to thermal energy (heating).For some surfaces, notably liquids, it can be much less than others, notably rough solids. There are different types of friction, and rolling friction is usually less than sliding friction. Lubricants are used to reduce friction by adding a layer of smoother or liquid material between surfaces.

What is different between static friction and kinetic friction?

Between any two body surfaces in contact there acts an frictional force. A friction can operate between a given pair of solids, between a solid and fluid or between a pair of fluids. There are two types of frictional forces : kinetic and static friction. When two bodies in contact move with respect to each other , rubbing the surfaces in contact the friction between them is called kinetic friction. The directions of frictional forces are such that it opposes the relative motion. Friction forces can also act between two bodies which are in contact but not moving or sliding with respect to each other. The friction in such case is static friction.

A force that opposes motion between two surfaces that are in contact?

First of all, if you just google the question, you will get the answer. Similarly, this question has been asked on answers.com multiple times (and answered). So maybe try that next time before asking the question. And the answer is Friction.


What force opposes motion whenever two surfaces rub againest each other?

friction is the force which opposes relative motion between the bodies.All the surfaces are not perfectly smooth,there will be some irregularities in its surface,when other bodies rub on this surfaces it will stucj in these irregular spaces this is called friction,there is allot of definitions about friction,but this theory is universly accepted,there are twko types of friction 1)static friction:its the friction when two bodies are at rest 2)kinetic friction:when two bodies are in motion when rubbing kinetic friction is acting


What is the Force between two nonmoving surfaces called?
